I think its an issue with your backup and restoring only brings back the issue. An easy way of testing is to (1) remove BlackBerry Messenger, (2) if you did a remote backup, remove that e-mail account from the BlackBerry, (3) reinstall the BlackBerry Messenger and then add a contact manually and see if the picture comes up. If it does, then you can restore from the local backup, write down all your contact pins and then do steps 1-3 and you should be fine.
